Abstract (en)
[origin: EP1742205A2] A magnetic recording medium including a magnetic layer 93 containing ferromagnetic powder and a binder, a support 91, and a backcoat layer 94, provided in this order, and being obtained by slitting to width a magnetic material of broad width and continuous length. The magnetic recording medium has no ridge protruding above the surface plane of the magnetic layer along the slit edge thereof. The magnetic recording medium achieves large recording capacity, is free from the tape pack problems such as appearance of a radial pattern and the output reduction problem, produces no fine scrapings in high speed running, which would cause head clogging and dropouts, thereby exhibiting good running durability and electromagnetic characteristics, and is particularly useful for computer data storage applications.
